"They're only having sex when I'm dead," O'Connell, 34, joked to Entertainment Tonight on Thursday. "If they don't date boys at all and just want to be infatuated with their father, that's what I'm really going for. The nunnery!"
Still, the actor says he's thrilled to have girls, for whom he and Romijn, 35, are considering rhyming names. "I think I'm going to be good [at] raising girls," he said. "I can't wait. They're going to be tough chicks."
As for O'Connell's No.-1 tough chick, Romijn is "doing great," he says, and "getting big ... Rebecca is the most beautiful thing that ever happened to the O'Connell family tree."
